SHEET DELIVERY AND STACKER.

To all whomit mag concern:

ACKERMAN, a citizen of the United States, residing at .llo. 1416 Blair street, Salt Lake City, in

the county of Salt Lake and State of Utah,

have invented a new and useful Sheet De- 'livery and Stacker Specially Adapted for Use on 'All Standard or Regular Drum Back-Delivery Printing-Presses, of which the following is a specification.

My invention'relates to improvements in the mechanism used for the purpose of deliveryand stacking of the printed sheets on all standard orregular drum back delivery printing, presses, in which my device takes the placerof all the complicated machinery comprising the fly system of sheet delivery and the ogger system ofsheet stacking; and the objects of my improvement are, first, to secure a a contrivance containing no small or delicately constructed parts, which are liable to need repairing or replacement; second, to stack the sheets automatically as they are delivered; third, to eliminate all risk of streaking the surface of the printed sheet, especially on illustrated matter; fourth, economy" in floor space by assembling the table inside the frame of the printing press instead of it being on the floor; fifth, to secure an easier means of access to the form,

for the purpose of making corrections 1n the type or cleaning the same. I attain these objects by the mecha nism illustrated in the following drawings.

Figure 1 is an elevation of my improvement. Fig. 2 is an elevation of the sliding gage and sliding gage iron, together with the necessary accessories. (Two of these sliding ages are used on each of my. improvements). Fig. 3 is an edge and plan view of the reel cam, together with theshoulder by which it is connected to the frame of the press; the particular shape'which l have given to the said reel cam is responsible for the release of the printed sheets by the best moment for the purposes of my invention. Fig. 4 is a front perspective view of my invention in position to deliver and stack the printed sheets. Fig.

5 is a front perspective view of my invention, showing the front table raised in and held by the tableregulators, for the purpose of giving easier access to press.

Specification of Letters Patent. application filed September 10, 1912. Serial No. 719,653.

better delivery of the sheets by the form in the r Patented Norm-11,1913.

Similar letters refer to similar parts throughout the several views.

The table, of wood, A; the table supports (iron) F; the table regulators (iron) G;

the finger board (hard wood) B; the table braces (wood) I and the butt hinges J, constltute the framework of my invention. The

table A. is constructed in two parts, hinged together with four or more two inch butthing'es J, and is beveled on the back so that the finger boar-dB forms an angle of about 76 degrees with the top of the rear portion of the table A. The top edge of the finger board B is scalloped to allow the free action of the reel wheels of the printing press, a a Fig. 4:, and the fingerboard B is also grooved onits front face to accommodate the finger irons D flush with the wood. The finger irons D and the fingers E are formed of one length of metal, but for convenience I prefer to call the portion of said strip of metal which is sunk in the finger board B. as hereinbefore described, as finger iron I). and the portion which is bent forward and over the table A, and is designedto intercept and deliver the printed sheet upon the table A. is designated as finger E, Figs. 1 and 4. The finger irons D are screwed into position as before described on the finger boardl'i, hc- 1 tween the reel wheel scallops, and the fingers E are bent and shaped so as to intercept the prihted sheet between the rims of the reel wheels and the reel gripper shaft, so that the edge of the printed sheet is under the fingers E about one and'oue-h alf inches when released by the reel grippers, Fig. 1. The reel cam, shown in Fig. 3 is 50* constructed that the reel grippers do not release their hold upon the sheet until the front edge of the sheet is drawn under the fingers E about one and one-half inches. The shoulder. y, is-connected to the frame of the press at the same place and in the same manner as the reel cam heretofore in use.

The sliding side gage irons, K, are cast in one piece, the winged portion is fastened to the sliding side gage, C, by screws, (see Figs. 1 and 2) and the lower part has a "threaded hole, in which the thumb screw,

hT, after heing fitted with the nut, M, and the washer, L is screwed from underneath the table, A, at the point 8, s, which is a .rahhetcut to accommodate the said side ,(gage iron, K. Two of these sliding gages are used on each table, and together with the loose gage, 0, Fig. '1 and the finger board, B, form the essential parts of my stacking device. The loose gage, O, is constructed of a thin sheet of metal, but is not indispensable for the correct stacking of the printed'sheets. Q w

I attach my improvement to the printing press in the following mannerz+The bolts heretofore used to secure the reel shaft boxes to the frame of the printing press are removed and replaced by longer ones of the same make, which are passed through the holes, Q, at the top ends of the table supports, F, and are secured by nuts on the bolts securing the saidreel shaft boxes. The table support, F, is made all in one piece and extends under the rear end of the table, A, (to which it is secured with screwsy and is then bentupward at right angles so as to form two arms (or hanging supports for thetable) as shown in Figs. 1 and 4: at F. The table regulators, G, are secured by bolts which pass through the frame of the press and the holes shown in the top end of the regulators, G, Fig. 1, and is better illustrated in Fig. 5. The front end of the table A, is strengthened by braces I, I, Fig. 5,

and plates having a thumb-screw shaped projection H, on the outside end are secured by screws to the underside of the said braces I, I, and the table A (front end) is supported at any required angle by means of the table regulators, G, the plates, H, and

the butt hinges, 'J, see Figs. .4 and 5.

The principle upon which myinvention is.

successfully worked is as follows: The printed sheet is taken from the cylinder by the reel grippers, the same as heretofore, with the exception that the reel cam, shown in.

Fig.-3, causes 'the'release of the sheet by the reel grippers at a point eight or nine inches below the pointof release needed by the fly system, but in my invention there are no fiysticks to rub against and mar the printed sheet as so often happens in illustrated' matter, instead, the stationary fingel-s, E, (four or more, accordingto. size and width of printing press) are so arranged as to interceptthe forward edge of the printed sheet between the rim of the reel wheels and the reel gripper shaft and the sheet isthen carried forwardjand under the fingers, E, about one andLpne-half'inches before being released by the said grippers. \Vhen released, the sheet is carried forward to the front face of the finger board, 'B, by its own momentum and the current of air which the rotation of the sheet itself upon 'the reel wheels has caused to circulate, the

sheet then falls from the reel wheels onto the table A, and is stacked between the side sliding gages C, and. the finger board B, with no other neededattentior than the fixing of the sliding gages to meet the requirements of the width of sheet being printed.

Previous to my invention, if a correction was needed inthe type when the form was in the press it was necessary torun the form to the front of the press, and'in many instances, to remove the ink rollers. The ease with which access to the form is given by my invention is well illustrated in Fig. 5, in which the table A, is shown raised in the table regulators G (the fly, table, which formerly occupied several feet of floor space at the back of thepress being dispensed with and replaced-in. all its usefulness by the table A).

What I claim asmy invention, and desire to secure. by Letters Patent, is-

1.111 a dense of-the class described the combination of a U-shaped table support detachably secured to the frame of a print ing press; a section of a table superimposed on said support; another portion of saidtabl'e hinged thereto;' r egulators to adjust one edge of the last mentioned section of said.

table; a finger board secured to and inclined over a portion of said first mentioned side 'guidesadjustable on said table.

2. Ina device of the class described the combination of a U-shaped table support securedto the frame of a printing press; a

table section superimposed thereon; another portion of said table hinged thereto regulators engaging therewith to adjust the .height of one edge (if said table; a finger board secured to andinclined toward said table; fingers secured to .said board; side and front guides on said table adapted to direct a sheet of printed matter on to said table; and a cam to release said sheet from the reel of the printing press when it is en gaged by said fingers.

In testimonywhereof I have my name to this specificationin the presence of two subscribing witnesses.
